Strategies for managing earthquakes

  • Predict the occurrence of earthquakes-when, where and their possible magnitude

  • Watch for the surface changes such as bulges on the ground

  • Measure amount of argon and radon gas found in the soil above a fault. These gases seem to increase before imminent earthquakes

  • Pump water and lubricants into fault. This allows the rock to slip past each other, creating a number of smaller but less damaging earthquakes.

MINIMISING DAMAGE FROM EARTHQUAKES

Most deaths are caused by the collapse of buildings, these can be minimized if:

  • Present building are reinforced

  • New building are designed to withstand earthquake shock

  • Tall building are not building in high risk areas.

  • Single storey are built instead of multi-storey building.

  • Evacuation route and passage ways ( for rescuer and medical team) are considered in land use planning.

Earthquake region

  • The greatest concentration of earthquakes is found around the Pacific Ocean.

  • Another stretches from the Mediterranean sea to the Hilmalayas.

  • Both areas are the plates moving towards each other.

  • The volcanic belt coincide with the major earthquake zone.THE EARTHQUAKE REGIONS
